Modular outdoor classroom desks

ABSTRACT

A set of modular classroom desks configured for outdoor use is presently described. Each classroom desk includes a bench seat; a table unit having a top surface; and first and second legs, each of which is coupled to both the bench seat and the table unit. The classroom desks of the set are configured to be releasably attached together in either a side-by-side orientation or a face-to-face orientation. In the side-by-side orientation, the top surfaces of the classroom desks form a planar tabletop surface, and the bench seats of the classroom desks form a planar seating surface. In the face-to-face orientation, the top surfaces of the classroom desks form a planar tabletop surface. In this manner, a number of classroom desks may be attached together, for instance to form a picnic table.

This application claims priority to U.S. Provisional Patent Application No. 63/064,521, filed on Aug. 12, 2020, the entirety of which is incorporated by reference herein.

BACKGROUND

As the present COVID-19 pandemic continues, schools are increasingly looking for ways for make the classroom experience safer for teachers and students alike. One option that is available in some regions is the use of outdoor classroom spaces. Most schools, however, are not presently equipped with outdoor classroom furnishings. In fact, most schools at best have picnic tables in outdoor locations. While useful for lunch and recreational activities, those picnic tables are less than ideal for use in an outdoor classroom. Embodiments of the present invention are directed to desks having a variety of features that render them particularly suitable for an outdoor classroom.

While some outdoor classrooms may be maintained and used regularly beyond the present pandemic, it is also expected that many outdoor classrooms will only be used in special circumstances, e.g. a pandemic, damage to a classroom building, a major renovation project, etc. Accordingly, embodiments of the present invention are directed to modular outdoor desks that may be converted from classroom desks into a picnic table, thereby providing a school or municipality with a useful structure even when the desks are not needed for an outdoor classroom.

SUMMARY OF THE INVENTION

Embodiments of the present disclosure are directed to a classroom desk or a set of classroom desks configured for outdoor use. Each classroom desk includes a seat, such as a bench seat; a table unit having a top, working surface; a first leg coupled to both the seat and the table unit and having a portion that rests on a ground surface; and a second leg coupled to both the seat and the table unit and having a portion that rests on a ground surface. The first and second legs may support the seat and the table unit at desired heights and at a desired distance from one another to provide a comfortable reading and writing environment. Desirably, the first and second legs are located at opposite sides of the classroom desk, so that a student seated on the seat will have adequate room to place his or her legs between the first and second legs.

In some embodiments, the classroom desks may be modular. For instance, in some embodiments, a first classroom desk and a second classroom desk may be configured to be releasably attached together in either (1) a side-by-side orientation, in which the top surface of the first classroom desk and the top surface of the second classroom desk form a planar tabletop surface, and the bench seat of the first classroom desk and the bench seat of the second classroom desk form a planar seating surface, or (2) a face-to-face orientation, in which the top surface of the first classroom desk and the top surface of the second classroom desk form a planar tabletop surface. In this way, classroom desks may be arranged as needed or desired to best fit a given outdoor classroom space.

In some embodiments, the classroom desks may also be configured so that four or more desks may be attached together to form a picnic table that looks and operates like a conventional rectangular picnic table. For instance, a first desk and a second desk may be attached in a side-by-side orientation in which a seat of the first classroom desk and a seat of the second classroom desk form a first planar seating surface. Similarly, the third desk and the fourth desk may be attached in a side-by-side orientation in which a seat of the third classroom desk and a seat of the fourth classroom desk form a second planar seating surface. The first desk and the third desk may be attached in a face-to-face orientation and the second desk and the fourth desk may be attached in a face-to-face orientation. In this way, the top surface of the first classroom desk, the top surface of the second classroom desk, the top surface of the third classroom desk, and the top surface of the fourth classroom desk may together form a table having a planar tabletop surface, with the first and second planar seating surfaces being located on opposite sides of the table, as in a conventional picnic table.

In some embodiments, two classroom desks—i.e., first and second classroom desks—may be configured to be secured together in a face-to-face orientation. For example, each table unit may comprise a front face having one or more apertures configured to receive one or more fasteners. When placed in a face-to-face relationship, at least one of the one or more apertures in the front face of the table unit of a first classroom desk may be aligned with at least one of the one or more apertures in the front face of the table unit of a second classroom desk. A fastener, e.g. a bolt, a screw, a clip, or the like, may be inserted through the aligned apertures, thereby securing the table unit of the first classroom desk and the table unit of the second classroom desk together. Alternatively, first and second classroom desks may be configured to be secured together in a face-to-face orientation through one or more connectors, such as clips, clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc. The connectors may be built-in, e.g. permanently attached to or integral with an element of the first and/or second classroom desk, such as the front face of the table unit, the underside of the table unit, or the first and second legs, or attachable to elements of the first and second classroom desks, such as the front faces of the table units, the undersides of the table units, and/or the first and second legs of each classroom desk.

In some embodiments, an optional front shield may be included at the front of a classroom desk. This front shield may also operate as a front divider when installed between first and second classroom desks arranged in a face-to-face orientation. The front shield/divider may comprise a plastic sheet material that extends upward of the table unit of the classroom desk or the tabletop surface formed by the table units of the first and second classroom desks. The front shield/divider may be made of a transparent material, such as polycarbonate, polymethyl methacrylate (Plexiglass®), or the like. The front shield/divider may be useful for purposes of social distancing, such as during a pandemic. In some embodiments, the front shield/divider may also be configured to be used in learning and/or artistic activities, e.g. as a dry-erase board.

The front shield/divider may be secured to the front of a table unit in much the same way that the table units of two classroom desks may be secured in a face-to-face orientation. For instance, the front shield/divider may have one or more apertures that are configured to receive one or more fasteners. When the shield/divider is attached to the front of a single classroom desk, one or more apertures in the front shield may be aligned with one or more apertures in the front face of the table unit and then a fastener, e.g. a bolt, a screw, a clip, or the like, may be inserted through each of the aligned apertures, thereby securing the front shield to the table unit of the classroom desk. Alternatively, in other embodiments, the shield/divider may be secured to the front of the table unit using one or more connectors, such as clips, clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc.

When the shield/divider is attached between the table units of two classroom desks, one or more apertures in the front divider may be aligned with one or more apertures in the front face of the table unit of the first classroom desk and one or more apertures in the front face of the table unit of the second classroom desk. A fastener, e.g. a bolt, a screw, a clip, or the like, may then be inserted through each of the aligned apertures, thereby securing the table unit of the first classroom desk and the table unit of the second classroom desk together, with the front divider sandwiched and secured between the two table units. Alternatively, in other embodiments, the shield/divider may be secured to the two table units using one or more connectors, such as clips, clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc.

In some embodiments, two or more classroom desks—e.g. first and second classroom desks—may be configured to be secured together in a side-by-side orientation. For example, each table unit may have a side face with one or more apertures configured to receive one or more fasteners. When attached in a side-by-side orientation, one or more apertures in the side face of the table unit of the first classroom desk may be aligned with one of the one or more apertures in the side face of the table unit of the second classroom desk. A fastener, e.g. a bolt, a screw, a clip, or the like, may be inserted through each of the aligned apertures, thereby securing the table unit of the first classroom desk and the table unit of the second classroom desk together. Alternatively, first and second classroom desks may be configured to be secured together in a side-by-side orientation through one or more connectors, such as clips, clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc. The connectors may be built-in, e.g. permanently attached to or integral with an element of the first and/or second classroom desk, such as the side face of the table unit, the underside of the table unit, or at least one of the legs, or attachable to elements of the first and second classroom desks, such as the side faces of the table units, the undersides of the table units, and/or at least one of the legs of each classroom desk.

Additionally or alternatively, each seat may have a side face with one or more apertures configured to receive one or more fasteners. When attached in a side-by-side orientation, one or more apertures in the side face of the seat of the first classroom desk may be aligned with one or more apertures in the side face of the seat of the second classroom desk. A fastener, e.g. a bolt, a screw, a clip, or the like, may be inserted through each of the aligned apertures, thereby securing the seat of the first classroom desk and the seat of the second classroom desk together. Alternatively, first and second classroom desks may be configured to be secured together in a side-by-side orientation through one or more connectors, such as clips, clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc. The connectors may be built-in, e.g. permanently attached to or integral with an element of the first and/or second classroom desk, such as the side face of the bench seat, the underside of the bench seat, or at least one of the legs, or attachable to elements of the first and second classroom desks, such as the side faces of the bench seat, the undersides of the bench seats, and/or at least one of the legs of each classroom desk.

In some embodiments, an optional side shield may be included at the side of a classroom desk. This side shield may also operate as a side divider when installed between first and second classroom desks arranged in a side-by-side orientation. The side shield/divider may comprise a plastic sheet material that extends upward of the table unit of the classroom desk or the tabletop surface formed by the table units of the first and second classroom desks. The side shield/divider may also extend above the seat of the classroom desk or the planar seating surface formed by the seats of the first and second classroom desks. Indeed, in some embodiments, the side shield/divider may even extend rearward of the seat of the classroom desk or the planar seating surface formed by the seats of the first and second classroom desks. The side shield/divider may be made of a transparent material, such as polycarbonate, polymethyl methacrylate (Plexiglass®), or the like. The side shield/divider may be useful for purposes of social distancing, such as during a pandemic. In some embodiments, the side shield/divider may also be configured to be used in learning and/or artistic activities, e.g. as a dry-erase board.

The side shield/divider may be secured to the side of a classroom desk in much the same way that the table units and/or seats of two classroom desks may be secured in a side-by-side orientation. For instance, the side shield/divider may have one or more apertures that are configured to receive one or more fasteners. When the shield/divider is attached to the side of a single classroom desk, one or more apertures in the side shield may be aligned with one or more apertures in the side face of the table unit and/or one or more apertures in the side face of the seat and then a fastener, e.g. a bolt, a screw, a clip, or the like, may be inserted through the aligned apertures, thereby securing the side shield to the table unit and/or the seat of the classroom desk. Alternatively, in other embodiments, the shield/divider may be secured to the side of the table unit and/or the side of the seat using one or more connectors, such as clips, clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc.

When the shield/divider is attached between two classroom desks, one or more apertures in the side divider may be aligned with (1) one or more apertures in the side face of the table unit of the first classroom desk and one or more apertures in the side face of the table unit of the second classroom desk, (2) one or more apertures in the side face of the seat of the first classroom desk and one or more apertures in the side face of the seat of the second classroom desk, or (3) both (1) and (2). A fastener, e.g. a bolt, a screw, a clip, or the like, may then be inserted through each of the aligned apertures, thereby securing the first classroom desk and the second classroom desk together with the side divider sandwiched and secured between the two table units, the two seats, or both. Alternatively, in other embodiments, the shield/divider may be secured to the two table units, the two seats, or both using one or more connectors, such as clips, clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc.

In some embodiments, a classroom desk may comprise a removable writing surface that is releasably attachable to the table unit and which covers at least a portion of the top surface of the table unit.

In some embodiments, and particularly where a set of classroom desks are configured to be assembled together to form a picnic table, the table unit of the classroom desks may have a plurality of apertures. For example, the table unit and the seat of a classroom desk may each be made from a coated perforated material, such as a perforated sheet steel that is coated with a weather-resistant and thermal insulating material such as PVC or TPV. The apertures provide drainage while the coating provides weather resistance. The coating may also be selected from a variety of colors, allowing for the creation of classroom desks having a school's official color or colors. In other embodiments, the table unit and the seat may each be made from a heavy duty plastic such as high-density polyethylene (HDPE) or the like and provided with drainage apertures.

While this tabletop surface may be ideal when the desks are assembled to form a picnic table, however, it is far less suitable for use as a writing surface. A removable writing surface, in contrast, may have a smooth, continuous upper surface that is ideal for writing. The removable writing surface may also be weather-resistant. For example, in some embodiments, the removable writing surface may be made of a powder-coated sheet steel or a heavy-duty plastic such as high density polyethylene (HDPE) or the like. The removable writing surface may be attached to the table unit when desired and removed from the table unit when not desired.

The removable writing surface may be releasably attached to the table unit in any of a variety of manners. In some embodiments, the writing surface may comprise an upper surface, a first side face extending downward from the upper surface, and a second side face extending downward from the upper surface. Each of the first side face and the second side face may include one or more connection elements by which the writing surface is securable to the table unit. For instance, at least one, and desirably each of the first side face and the second side face may comprise one or more clips that clip onto the respective side face of the table unit. Or at least one, and desirably each, of the first side face and the second side face may include one or more apertures which are configured to align with one or more apertures in the respective side face of the table unit and receive a fastener. In other embodiments, the removable writing surface may be secured to the table unit using one or more connectors, such as clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc.

In some embodiments, the writing surface may comprise an upper surface, a front face extending downward from the upper surface, and a rear face extending downward from the upper surface. Each of the front face and the rear face may include one or more connection elements by which the writing surface is securable to the table unit. For instance, at least one, and desirably each, of the front face and the rear face may comprise one or more clips that clip onto the respective front and/or rear face of the table unit. Or at least one, and desirably each, of the front face and the rear face may include one or more apertures which are configured to align with one or more apertures in the respective front and/or rear faces of the table unit and receive a fastener.

In some embodiments, the classroom desk may comprise a backrest. In some embodiments, the backrest may be integral with or permanently secured to the bench seat. In some embodiments, however, the backrest may be removable. For instance, the backrest may comprise a frame element that may be affixed to the underside of the bench seat.

In some embodiments, the backrest of a first classroom desk may be configured to be secured to the backrest of a second classroom desk when the first and second desks are placed in a side-by-side orientation. This may be in addition or as an alternative to the securement of the table units and/or the bench seats of the first and second classroom desks, as described above.

For example, each backrest may have a side face with one or more apertures configured to receive one or more fasteners. When attached in a side-by-side orientation, one or more apertures in the side face of the backrest of the first classroom desk may be aligned with one or more apertures in the side face of the backrest of the second classroom desk. A fastener, e.g. a bolt, a screw, a clip, or the like, may be inserted through each of the aligned apertures, thereby securing the backrest of the first classroom desk and the backrest of the second classroom desk together. Alternatively, the backrests of first and second classroom desks may be configured to be secured together in a side-by-side orientation through one or more connectors, such as clips, clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc. The connectors may be built-in, e.g. permanently attached to or integral with an element of the first and/or second classroom desk, such as the side face of the backrest, the rear side of the backrest, or at least one of the connectors by which the backrest is connected to the bench seat, or attachable to elements of the first and second classroom desks, such as the side faces of the backrests, the undersides of the backrests, and/or at least one of the connectors by which the backrests are connected to the bench seats.

In some embodiments, the side shield/divider may be secured to the side of a backrest. This may be in addition or as an alternative to the securement of the side shield/divider to the table unit and/or the bench seat of a classroom desk, as described above.

For instance, the side shield/divider may have one or more apertures that are configured to receive one or more fasteners. When the shield/divider is attached to the side of a single classroom desk, one or more apertures in the side shield may be aligned with one or more apertures in the side face of the table unit and/or one or more apertures in the side face of the seat and/or one or more apertures in the side face of the backrest and then a fastener, e.g. a bolt, a screw, a clip, or the like, may be inserted through each of the aligned apertures, thereby securing the side shield to the table unit and/or the seat and/or the backrest of the classroom desk. Alternatively, in other embodiments, the shield/divider may be secured to the table unit and/or the seat and/or the backrest using one or more connectors, such as clips, clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc.

When the shield/divider is attached between two classroom desks, one or more apertures in the side divider may be aligned with (1) one or more apertures in the side face of the table unit of the first classroom desk and one or more apertures in the side face of the table unit of the second classroom desk, (2) one or more apertures in the side face of the seat of the first classroom desk and one or more apertures in the side face of the seat of the second classroom desk, (3) one or more apertures in the side face of the backrest of the first classroom desk and one or more apertures in the side face of the backrest of the second classroom desk, or (4) any combination of (1) through (3). A fastener, e.g. a bolt, a screw, a clip, or the like, may then be inserted through each of the aligned apertures, thereby securing the first classroom desk and the second classroom desk together with the side divider sandwiched and secured between the two table units, the two seats, the two backrest, or any combination thereof. Alternatively, the shield/divider may be secured to the table units and/or the seats and/or the backrests of the first and second classroom desks using one or more connectors, such as clips, clamps, latches, swivel locks, magnetic connectors, the combination of a male connector and a female connector, etc. Alternatively, the side shield/divider may simply be sandwiched between the backrests of the first and second classroom desks.

In some embodiments, the classroom desk may also be configured to be usable by a student in a wheelchair without having to exit the wheelchair. For instance, the front of the classroom desk, i.e. the side opposite the bench seat, may be configured to accept a wheelchair. In some embodiments, therefore, the distance between the first leg and the second leg, i.e. the width, may be at least 30 inches (760 mm). Similarly, in some embodiments, the distance between the bottom surfaces of the first and second legs, which rest on a ground surface, and the underside of the table unit may be at least 27 inches (685 mm). In some embodiments, the distance between the bottom surfaces of the first and second legs, which rest on a ground surface, and the upper surface of the table unit may be 34 inches (864 mm) or less, alternatively 30 inches (760 mm) or less. For example, in some embodiments the distance between the bottom surfaces of the first and second legs, which rest on a ground surface, and the upper surface of the table unit may be between 27 inches and 34 inches, alternatively between 28 inches and 34 inches, alternatively between 27 inches and 30 inches, alternatively between 28 inches and 30 inches.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present disclosure are directed to a modular outdoor classroom desk 10 and/or to a set of such desks. One such embodiment is shown, for example, in FIGS. 1 to 6. The illustrated embodiment of the classroom desk includes a bench seat 11, a table unit 12 having a top surface 13, a first leg 14 coupled to both the seat and the table unit and having a portion that rests on a ground surface, and a second leg 15 coupled to both the seat and the table unit and having a portion that rests on a ground surface.

The bench seat 11 comprises an upper surface 41, on which a student sits, an underside, to which various connectors and other elements may be attached, and a flange that extends downward from the upper surface and that defines a front face 42, a rear face 43, and a pair of side faces 44. Each side face 44 may comprise one or more apertures 45, which may be used to attach a side shield and/or another classroom desks 10 in a side-by-side orientation, as described herein.

The table unit 12 comprises an upper surface 13 (also referred to as a top surface), an underside, to which various connectors and other elements may be attached, and a flange that extends downward from the upper surface and that defines a front face 52, a rear face 53, and a pair of side faces 54. Each side face 54 may comprise one or more apertures 55, which may be used to attach a side shield and/or another classroom desk 10 in a side-by-side orientation, as described herein. Similarly, each front face 52 may comprise one or more apertures 56, which may be used to attach a front shield and/or another classroom desk 10 in a face-to-face orientation, as described herein.

The bench seat 11 and the table unit 12 may be made of the same material or different materials. In some embodiments, including that illustrated in FIG. 1, the bench seat 11 and the table unit 12 are made of perforated sheet steel coated with a weather-resistant and thermal insulated PVC or TPV coating. In other embodiments, however, one or more of the bench seat 11 and the table unit 12 may be made of a different material, such as another metal or a heavy duty plastic material, such as high density polyethylene (HDPE). The coating or the plastic material may be provided in any of a variety of colors, meaning that the bench seat 11 and the table unit 12 may be either the same color or different colors.

The bench seat 11 may be provided with one or more apertures 16 running through it to allow for drainage. As shown in FIG. 1, for example, the bench seat 11 of the illustrated embodiment comprises a plurality of small apertures 16—here perforations—running through it. The table unit 12, and more particularly the top surface 13, may similarly be provided with one or more apertures 17 running through it to allow for drainage. As shown in FIG. 2, for example, the top surface 13 of the table unit 12 of the illustrated embodiment comprises a plurality of small apertures 17—here perforations—running through it. In other embodiments, no such apertures may be present.

The first leg 14 and the second leg 15 connect the bench seat 11 and the table unit 12. In the illustrated embodiment, for example, the each leg 14, 15 comprises a first end coupled to the underside of the bench seat 11 and a second end coupled to the underside of the table unit 12. Each leg also has a generally horizontal portion that separates the bench seat 11 and the table unit 12 and that rests on a ground surface. The generally horizontal portion may be secured to the ground surface, thereby fixing the classroom desk 10 in an identified location, such as is shown in FIG. 1. However in other instances, it may be desirable to allow the classroom desk 10 to be moved around, in which case the legs 14, 15 may be left unsecured. In other, non-illustrated embodiments, each of the first and second legs 14, 15 may comprise wheels which enable the classroom desk 10 to be wheeled to a desired location. The wheels may include conventional wheel locks, of the sort that would be understood by a person of skill in the art, by which the desk 10 may be locked in place at a desired location.

In other embodiments, a single, e.g. central, leg may connect the bench seat 11 and the table unit 12. In such embodiments, the leg may have a plurality of feet or other elements that extend outward from the leg to provide stability.

As shown in the illustrated embodiment, the first and second legs 14, 15 may be made of powder-coated metal, such as powder-coated steel. However, the first and second legs 14, 15 may be made of any of a variety of materials and take on a variety of configurations. They are not limited to the materials or design shown in the illustrated embodiment.

The first and second legs 14, 15 are spaced apart a desired distance to provide for an occupant of the seat to have adequate leg room. Similarly, the first and second legs 14, 15 support the bench seat 11 and the table unit 12 at desired heights to provide a suitable and comfortable working environment. In some embodiments, the classroom desk 10 may be configured to be usable by a student in a wheelchair. For instance, the front of the classroom desk 10, i.e. the side opposite the bench seat 11, may be configured to accept a wheelchair. In such embodiments, the distance between the first leg and the second leg 14, 15 may be at least 30 inches (760 mm). Similarly, in those embodiments, the distance between the bottom surfaces of the first and second legs 14, 15, which rest on a ground surface, and the underside of the table unit 12 may be at least 27 inches (685 mm).

The classroom desk 10 may also have a backrest 18. In some embodiments, such as that illustrated, the backrest 18 may be removable.

The backrest 18 comprises a front surface 61, on which a student rests his or her back, a rear side 62, to which various connectors and other elements may be attached, and a flange that extends rearward from the front surface 61 and that defines a top face, a bottom face, and a pair of side faces 64. Each side face 64 may comprise one or more apertures 65, which may be used to attach a side shield and/or another classroom desk 10 in a side-by-side orientation, as described herein.

The backrest 18 may comprise one or more frame elements 19 that connect the backrest to the bench seat 11. As illustrated, for example, a first end of each frame element 19 may be attached to the rear 62 of the backrest 18 and a second end of each frame element may be releasably attached to the underside of the bench seat 11. For example, the second end of each frame element 19 may have one or more mounting elements 20, each of which comprises one or more apertures configured to receive a fastener, e.g. a bolt, screw, clip, or the like, which secures the frame element to the underside of the bench seat 11. If one desires to remove the backrest 18, one simply need remove the fasteners.

In other, non-illustrated embodiments, the backrest 18 may be configured to be permanently connected to the bench seat 11, or the bench seat and the backrest may be integral.

The backrest 18 may be made of the same material(s) as the bench seat 11 and/or the table unit 12, or it may be made of a different material. Also, the backrest 18 may be the same color as the bench seat 11 and/or the table unit 12, or it may be a different color. For instance, in some embodiments, the bench seat 11 and the table unit 12 may be a first school color and the removable backrest 18 may be a second (and different) school color. The backrest 18 may also have a plurality of apertures, e.g. perforations, which may provide airflow and prevent the backrest from becoming overly hot.

In some embodiments, the rear side 62 of the backrest 18 may comprise a backpack hook 21. In some embodiments, the backpack hook 21 may extend away from the rear side 62 of the backrest 18 in a conventional manner. In other embodiments, the backpack hook 21 may extend away from the rear 62 of the backrest 18 and then loop back inward toward the backrest 18, such that the free end of the hook is shielded by the body of the hook. Accordingly, to hang a backpack in such an embodiment, a user would slide the hanger strap of the backpack up between the free and of the hook 21 and the rear surface of the backrest 18 and then move the hanger strap away from the rear surface of the backrest and onto the hook.

In some embodiments, the classroom desk 10 may comprise any of a variety of additional storage elements. For example, the classroom desk 10 may comprise a removable book and/or supplies (e.g. writing instruments, art supplies, water bottles, hand sanitizer, etc.) storage compartment that is attachable to the underside of the bench seat 11 or to the underside of the table unit 12. Or the classroom desk 10 may comprise a book and/or supplies storage compartment on the rear of the backrest 62, e.g. next to the backpack hook 21. Or the classroom desk 10 may comprise a removable book and/or supplies storage compartment that is attachable to the side 54 or the front 52 of the table unit 12, e.g. by using the same apertures 55, 56 by which the side or front of the table unit may be secured to a table unit of another classroom desk, as described herein.
